Patent CA-1092069-A (CA)
Inventor: DIAMOND GEORGE B
IPC: B65D83/14
Filed: 1977-05-12
Granted: 1980-12-23
Abstract: ABSTRACT OF THE DISCLOSURE         The invention provides a low pressure package or packaging system for dispensing a product of high viscosity, namely, 10,000 cps. or above at a pressure of only about 6-40 lbs. per sq. in. gauge (psig).  The low pressure re-duces the safety hazard to practically zero, reduces the cost of the container very substantially and minimizes the use of metals, plastics and other scarce materials.  The container is preferably provided with a barrier in the form of a piston, bag, disc or the like, to separate the product from the propellant.         By reason of the low pressure, the wall of the con-tainer can be relatively thin, of the order of 0.005 inch or less in the case of aluminum in 2-inch diameter containers.          The necessary thickness of materials other than aluminum (such as steel, plastic, paper board or laminates of metal, plastic and paper) will depend on their relative strengths.          The use of such thin-walled containers lowers the cost of the package and at the same time renders the wall so flex-ible and pliable that the wall conforms to the piston or disc barrier which helps to prevent by-pass or escape of propellant gas and also allows the pressure inside to smooth out any dents occurring during transportation.  The confor-mation of the wall to the barrier also permits almost com-plete expulsion of the product.         The valve is provided with a sealing disc or head secured to a tiltable stem.  The sealing disc is of consider-ably larger diameter than those of prior valves, and maybe three or four or more times the internal diameter of the stem.  The disc hinges on a small portion of the perimeter to provide a passageway for the product extending throughout 360°.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to a method for processing a tar contain-ing benzyl benzoate.  According to the invention a tar containing benzyl ben-zoate is processed by subjecting it to a hydrolysis or ammonolysis reaction. Thus the benzyl benzoate with a high boiling point which is difficult to separate from some tar components by distillation is converted into the benzyl alcohol with a considerably lower boiling point in addition to the benzoic acid or a salt or amide thereof, which differs considerably in chemical pro-perties from the benzyl benzoate and the tar components.  Pure benzyl alcohol can be recovered from the hydrolysed or ammonolysed mixture, e.g., by dis-tillation.  Benzyl alcohol is a useful product that is used in the scents and flavours industries,  Hence, it is achieved by the method according to the invention that a waste product with no applications so far is converted into a useful product.

Abstract: ABSTRACT OF THE DISCLOSURE      A gas burner control system including a main burner and a pilot burner for igniting the main burner wherein the pilot burner is ignited only when the thermostat is calling for heat and wherein a normally closed bimetal operated safety switch is effective to provide a trial ignition period for igniting the pilot burner.  An electrical resistance heater for effecting open-ing of the safety switch is in the gate circuit of a solid state switch and is energized in the absence of pilot burner flame.       The solid-state switch, when conducting, is effective to complete an electrical circuit through the safety switch to open a first valve and initiate gas flow to the pilot burner.  When pilot burner flame exists, the resistance heater is de-energized, the first valve is held open by means including a switch responsive to gas pressure downstream from the first valve, and a second valve, fluidically in series with the first valve and controlling the flow of gas to the main burner, is opened.

Abstract: ABSTRACT OF THE DISCLOSURE           A furnace has a self-recuperative burner fitted into its wall.  The hot products of combustion of air and fuel fed to the combustion zone of the burner are directed into the furnace in one direction by operation of the burner, either along the longitudinal axis of the burner outlet port or trans-versely with respect to that axis.  The inlet port through which gases are directed from the furnace interior into the exhaust system of the burner is spaced from the outlet port and aligned so that those gases enter the burner along a path which converges with the path of the gases that are directed into the furnace by the burner.  Hence the hot gases directed into the furnace by the burner are caused to circulate widely within the furnace in order to obtain access to the inlet port to be exhausted from the furnace.
